Sudbury (/ˈsʌdbəri/, locally /ˈsʌbəri/) is a market town in Suffolk, England, on the River Stour near the Essex border, 60 miles (97 km) north-east of London. At the 2011 census, it had a population of 13,063. It is the largest town in the Babergh local government district and part of the South Suffolk constituency.
Sudbury was an Anglo-Saxon settlement from the end of the 8th century, and its market was established in the early 11th century. Its textile industries prospered in the Late Middle Ages, the wealth of which funded many of its buildings and churches. The town became notable for its art in the 18th century, being the birthplace of Thomas Gainsborough, whose landscapes offered inspiration to John Constable, another Suffolk painter of the surrounding Stour Valley area. The 19th century saw the arrival of the railway with the opening of a station on the historic Stour Valley Railway, and Sudbury railway station forms the current terminus of the Gainsborough Line. In World War II, US Army Airforce bombers operated from RAF Sudbury.
Today, Sudbury retains its status as a market town with a twice-weekly market in the town centre in front of St Peter's Church, which is now a local community point for events such as concerts and exhibitions. In sport, the town has a semi-professional football club, A.F.C. Sudbury, which competes at the seventh level of the football pyramid.
